The Fermi Paradox – Cameron Klein – Blog Post #7

Posted on April 24, 2024 by Cameron Klein

Humans have never left the Milky Way. Therefore, it is really difficult to know if life truly exists beyond our galaxy. However, if humans were to become interstellar travelers (even if traveling at relatively slow speeds), we would be able to have humans all around the Milky Way in just a few million years! Though […] Continue reading →

Blog #4 – Evidence for the Existence of Dark Matter

Posted on March 7, 2023 by constellationsarentreal

Dark Matter is a fascinating topic, yet we know so little about it. Regardless, a good amount of evidence exists that indicates dark matter is real. One pertains to the flatness of rotation curves for spiral galaxies at extended distances. The graph does not drop off, but rather, continues in (essentially) a flat rotation curve, […] Continue reading →

Gravitational Lensing!

Posted on February 11, 2023 by brandodan

In class, we’ve been diving into the world of gravity and light. We have covered Newton’s laws of motion and the effects of gravity in our universe. As well, we’ve explored how light behaves and travels through space. Now I want to introduce another intriguing topic that combines the two –gravitational lensing! Gravitational lensing occurs […] Continue reading →

Blog #1: The Power of Ten

Posted on January 23, 2023 by reidwalker87

The Power of Ten video puts into perspective the miniscule size of not only individuals on Earth but of the Solar System entirely. At only 3 minutes into the video, we were already far beyond the Solar System with so much time remaining. Not only was I struck by the immense scale of the universe, […] Continue reading →
